At a glance
The build, by the numbers.
This 42′x25′x12′ all-vertical A-frame colonial barn features a 14g frame and 29g panels, with one 8′x7′ roll-up door and two 10′x10′ roll-up doors. It is ideal for agricultural storage or workshop use.
At 42′ across, the span leaves usable floor on both sides of a center aisle. Because it comes closed in, it secures what is inside rather than only sheltering it. There is no walk-in door in this configuration, which is the usual first addition if you plan to work inside. 42′x25′x12′ is a size that usually goes up as a body shop and detail bay combo. Second most common: an event hall.

What's it for
Same shell, very different jobs.
A 42′x25′ gets specified differently depending on what goes in it — door placement, openings, leg height, whether it closes in. Tell us the job and we'll spec it to that instead of handing you a blank form.

Questions
Good to know.
A specialist can walk you through this exact build over the phone in a few minutes.
For a closed building this size, yes. The pad wants to match the 42′ x 25′ footprint, be level, and be cured before delivery, because the walls of a 42′ x 25′ x 12′ seal down onto it and the door track depends on it being flat. Pour it yourself or have a local contractor do it ahead of the install date.
Eave height. On a 42′ x 25′ x 12′ that means 12′ of straight wall before the roof starts to pitch up, so usable height at the walls is 12′ and the center is taller. Measure your equipment against the eave figure if it sits near a sidewall.
This one is specified with (2) 10′x10′ roll up Doors, (1) 8′x7′ roll up door. That is the opening itself, so measure whatever has to drive through against the door rather than against the 42′ width. Door sizes are not fixed — if what you are parking is tight, say so on the quote, because adding or resizing an opening up front is cheaper and cleaner than cutting one in later.
The sheet for this build states fully enclosed certified all vertical A-Frame colonial barn. Anything about how it closes in — which ends, which sides, where the doors land — is settled on the quote, so if you need a different arrangement it does not have to be a special order.
$19,552 covers the building, the delivery and the install crew. It does not cover site work — leveling the 42′ x 25′ area, or pouring a slab if this one is going on concrete. Those happen before install day. Options and local wind and snow certification are the two things that move the number.
The 20 years figure is rust-through on the frame, which is the structural cover and the one that matters over the life of a 42′ x 25′ building. Separately, the install itself is warranted 30 days, so anything that looks wrong when the crew leaves should be raised inside that window.
This page prices the 42′ x 25′ x 12′ as built, but width moves in 2-foot steps, length in 5-foot steps and leg height in 1-foot steps. Tell us the footprint you actually need and we price that build instead.

View all reviewsWe are building a barndominium and they delivered the shell on schedule. Our contractor said the framing was straighter than most stick-built shells he sees.

Loafing shed for the horses showed up exactly when they said it would. The crew leveled and anchored on uneven ground and didn't try to charge extra.

Hurricane-rated anchors and engineer-stamped drawings were ready when our county asked. Permit went through the first time.
